First Impressions: 2017 Yamaha YZ450F

After a moderate amount of changes in 2016, the 2017 model received a very short list of updates. This includes new tires, going from Dunlop's MX52 to the MX3S, new airbox mold better hide the zeus fasteners, and few internal engine parts that were updated for reliability.

This isn't too surprising after Yamaha added new intake and exhaust cams, improved ECU settings, an updated frame, lower footpegs mounts, a new triple clamp offset, and more to the 2016 model. A few of which made their way to the YZ250F, which gained most of the attention for 2017.
